ROLLER-SKATE.

SPECIFICATION formingpart of Letters Patent No. 284,187, dated September4, 1883.

- Application mea June 5,1883. (No model.)

To all whom, it may concern:4

Be it known that I, ROBERT HUDSON `COOMBs, of Belfast, in the county ofWaldo,

` j view, Fig. 5 a bottom view, Fig. 6. al'ongitudinal section, and Fig.7 a `transverse section, of one of the said roller-spindle supporters,the nature of which is hereinafter defined.

. This roller-spindle supporter contains not only a crucial elasticcushion interposed between its two sections, but has such sections`provided with mechanism by which a skater,

when `skating with the skate, can cause the wheel-spindlesof it toincline more or less to each other, in a manner to induce their wheelsto run in a circular or curved path rather than in\a straight.one, asthey will when the two spindles are parallel.

. The foot-support piece is shown at A as provided with two pairs ofwheels or rollers,

Shape. The two sections D and E are con` B B, each pair being adapted torevolve freely on one of two spindles, C, each of which eX- tendsthrough and fastened rmly in two lugs, c a, projecting `downward fromthe shorter arms of a cross, c, constituting with such lugs the lowersection, D, of the spindle-supporter, the upper section of suchsupporter being shown at E.

The section E is secured to the lower side.

Between the twosections 'D and E is the crucial or cruciforined elasticcushion F, the

body of each arm of which is cylindrical in nected by a pivotal screw,G, (which goes down through them and the cushion F,) and two nuts, g h,screwed on `such screw under neath the cross c, as represented.

From the above andthe drawings it will b e seen that thespindle-supporters of the two pairs of wheels are alike in construction,and H that the `inclined planes of each incline in a direction oppositeto those of the other. This being the case, when a skater with all therollers of his skate resting on the iioor desires to cause the skate tomove in a curvedor circular path he should incline hisfoot laterallyinward, soas to move downward the inner inclined planesof the two`spindle-supporters, and in like degree upward the outer inclined planesof such supporters. In sodoing the lower section of each of suchsupporterswill,

vby theiinclined planes of the upper section, be revolved or turned onits pivotal screw, wherej by the two spindleswillbe thrown out of par-Vallelism and made to incline toward each other, so as to cause thewheels to run in a curved. path.

The crucial elastic or vulcanized india-rub ber cushion constitutes foreach lower section, D, a bearing th atwill yield and allow the sectionto tip a little both lengthwise and widthwise,

-as in straight paths, as he may desire.

I claim- The roller-,skate spindle-supporter, substanstantially asdescribed, consisting not only of the section E, with its inclinedplanes, and

the crucial sections, D, but of the crucial elastic cushion or bearingF, arranged between the said two sections, the whole being connectedarranged and adapted `to operate essentially as set forth.
